AUTOMATIC TRAIN-STOP.

1 b all whom it may concern Be it 'known that I, JUDGE S. ihLLEN,

a citizen of the United States,and a resident of the city of New York, borough of Man hattan, in the county and State of New York, have invented a new and Improved Automatic Train-Stop, of which the following is a clear, full, and exact description.

My invention has for its object to provide an automatic train stop, having a hollow post, in which a shaft is journaled, a cap being secured to the top of theshaft, and having depending lugs, which engage stops on the post for limiting the movement ofthe cap and the shaft. The cap extends outward from the shaft, and has a depending peripheral member, for protecting the stops and lugs from the weathe Secured to the cap there is an extending arm, which is counterbalanced by a weight in the cap. This arm is adapted to be engaged by a contact member, carried by arms secured to a shaft, journaled'in a bearing on a locomotive or car, one of the arms being connected with a train pipe valve lever by a link, so that when the contact member strikes the extending arm it will rotate the shaft journaled in the bearing in the locomotive or car, to open the valve.

Additional objects of the invention will appear in the following complete specifica-.

tion, in which the preferred form of the invention is disclosed.

In the drawings similar characters of reference indicate corresponding parts in all the Views, in which- Figure 1 is a fragmentary view of a locomotive which carries the contact member for engaging the extending arm on the post for opening the valve in the train pipe; Fig. 2 is an enlarged view of my invention, parts being broken away, to show the construction; Fig. 3 is a plan view of Fig. 2, showing the parts carried by the locomotive; and Fig. 4 is a sectional view on theline 44 of F 2.

By referring to the drawings it will be seen that a hollow post 5 is provided, which has a base 6, bolted to a suitable support 7. In this hollow post 5 there is journaled a shaft 8, the shaft 8 also extending through an opening 9 in the support 7, and having its lower end 10 disposed below the said support 7. The upper end 11 of the shaft 8 is disposed above the upper end 12 of the post 5. To this upper end 11 of the shaft 8 there Specification of Letters Patent.

is secured a cap 13, having its top 14 round ed downwardly, so that any snow falling on the cap will slide therefrom. The cap 1 3 is held downwardly against the top 12 of the post 5, by means of the nuts 15, which mesh with a thread on the top of the shaft 8, and press down against the top of the cap 13. Between the cap 14 and the top 12 of the post 5 there are ball bearings 16. The cap 13 has a bottom member 17, which is intogral with the sides 18 of the cap 13, the bottom member 17 extending upward and in ward to a position adjacent the post 5. Depending from the bottom 17 there are lugs 19, which are adapted to engage the stops, formed by the top of the flanges 21, secured to the post 5.

It will be noticed that the sides 18 extend below the bottom 17 of the cap, and also below the lugs 19 to protect the said lugs 19 from the weather. It should also be noticed that the cap 13 has a threaded member 22, extending therefrom, with which meshes the inner thread 23 on the hollow arm 24. The side I having the threaded member 22, has a cavity 25, so that the other solid side 26 of the cap 13, will serve as a counterweight for the arm 24. v

To the bottom 10 of the shaft 8 there is secured a lever 27, to which wires or pipes, or other means 28, may be secured, for turning the shaft 8 in a manner readily understood.

The device which has been described is stationed at the side of the track, and is operated by turning the shaft 8, so that the arm 24 will be extended in the direction of the track, or will be disposed parallel to the track, as occasion may require. hen the arm 24 is extended, the lugs 19 are dis posed against the stop 21, so that when the contact member 29 comes in contact with the arm 24, the arm 24 will maintain its position, and the contactmember 29 will be moved in a manner which will now be described. This contact member is secured to the arms 30, which are spaced apart, and which, in turn, are secured to the shaft 31, journaled in the bearing 32, bolted to the side 33 of the locomotive or car. The lower arm 30 extends inward beyond the shaft 31, and its inner terminal 34 is curved inthe manner shown in Fig. 3 of the drawings. This inner terminal 34 is connected'with the lever 35 of a train "pipe valve 36, by means of the cap 13 of a link 37. It will therefore be seen that when the contact member 29 engages the extended arm 24, and the contact member 29 is moved with its arms 30, to rotate the shaft 31, the curved terminal 3 L of the lower arm 30 will, by means of the link 37, move the lever 85 forward, to open the train pipe valve 36, which will permit the escape of the air from the train pipe, and set the brakes on the train.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. In an automatic train stop, a bearing, a shaft journaled in the bearing, two arms spaced apart andsecured for moving the shaft, a contact member secured to the arms, a valve having a lever, one of the arms having a terminal extending beyond the shaft,

and a link connecting the terminal with the lever.

2. In an automatic train stop, a train pipe, a valve for controlling pressure in the train pipe, a vertical bearing, a shaft journaled in the bearing, two horizontally extending arms spaced apart and secured to the shaft, one of the arms having an inwardly extending terminal curved in the direction of the valve, a contact member carried by the arms and a link connecting the curved terminal with the valve.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
